FCC Accelerators and
Beam Physics Day
Y. Papaphilippou December 2nd, 2021
ABP – Accelerators & Beam PhysicsGroup Leader: Yannis Papaphilippou
2
• Conducting theoretical, numerical and experimental beam physics
studies, including operational support throughout entire CERN
Accelerator Complex and for upgrades (LIU, HL-LHC) or new projects
(AWAKE, CLEAR, CLIC, FCC, Muons, PBC, Medical), covering
• Design maintenance and operation of hadron sources.
• Linear and nonlinear optics and beam dynamics.
• Halo generation and collimation.
• Cooling, coherent and incoherent collective effects
• Development of accelerator physics computer codes
Also strongly involved in teaching and raising the next generation of accelerator physicists

Rationalization and modernization of
simulation codesProject launched to rationalize and modernize software for multiparticle simulations (aka
tracking)
→Moving from a heterogenous range of programs each with limited capabilities to an
integrated modular toolkit (Xsuite)
• Allows usage across injectors, LHC, HL-LHC and design studies (e.g. PBC, FCC)
• Enables exploitation of modern computing platforms (e.g. GPUs) for a wide range
of applications
• Strong simplification of development and maintenance process (removed several
duplications)
